Jens Biegert received his PhD from the Technical University Munich in 2001, and led the research group on ultrafast pulse generation and strong field physics at ETH Zurich from 2001 until 2006. In 2007 he was appointed ICREA Research Professor and heads the Attoscience and Ultrafast Optics group at the Institute of Photonic Sciences (ICFO). He has served on several conference panels, as guest editor for the J. Mod. Optics, as editorial board member of the Int. Journal on Atomic Molecular, Condensate & Nano Physics and the Journal Optics. He is fellow of the German National Academic Foundation, was recipient of a Marie Curie Fellowship in 2001, the OSA Allen Price in 2004, was named Research Assistant Professor in the USA in 2001 and Research Professor in 2012 and Fellow of the Optical Society of America OSA in 2015.
The aim of our research is the investigation of ultrafast events that are caused by electrons inside atoms, molecules and solids. The power of attoscience and ultrafast optics lies in the incredible time resolution to observe the triggering events that cause electronic rearrangement and ultimately lead, to molecular dissociation, chemical reactions, excitonic energy transfer or even biological function. Our research is diverse and includes pioneering development of new light sources that are key enablers for coherent soft-X-ray generation across the water window (300-500 eV) and attosecond emission below the atomic unit of time (24 as). In 2016, we took the first snapshots of how a bond breaks and how a proton gets ejected. Moreover, we established the first source of isolated attosecond soft X-ray pulses which achieves real-time measurements of electronic synamics on the attosecond scale in combination with the element selectivity.
